2,156,276 IUNITEDJSTATEHS PATENT OFFICE nasx STAND Jesse L Coen, Blnefleld, w'. Va. Application hlovernber 9, 1936, Serial No. 109,955 11 Claims. 01. 242-107) (Granted under theact of March 3, 1833, amendedfApril 30, 1928; 370 O. G. 757) Several embodiments of my invention are known to me but according to that by means of ,which the invention may be practiced, I provide a base l5 having recesses I6 (see Fig. 2) adapted for use as ink wells or as means for receiving ink wells; as containers for paper clips and the like or as means for retaining clip bowls; and as ash receivers or as means for receiving ash trays. The base is also provided with elongated depressions I! (see Fig. 3) adapted for use as retainers for pens and pencils.

Upon the base I5 is mounted a housing, one portion 9, of which is adapted to operably retain and house a pencil sharpener 29, and another portion, 2|, of which is adapted to operably contain a spring rewind reel 22. The portion 2| is attached by suitable fastening means 22a to the base l5 and carries the portion l9 in axial alignment at one end.

Upon housing 2| is mounted a lamp shade 23 which projects over housing l9 .and is provided with a socket 24 to which a light bulb 25 may be operably connected. The socket is operably con- ,nected to an electrical conduit 26 whichpreferably, but not necessarily, passes from within the shade 23, into and through housing 2|, and thence passes into and extends from-the base ii for connection to a source of electrical power.

The extreme ends of housings l9 and 2| are provided with end closures 21 and 28, respectively, the end closure 28 on housing 2| being removably retained by means of key-hole type bayonet slots 29, provided therein, which engage screws 30 protruding from the 'edge of housing 2|. Housing I9 is also removably attached to housing 2| by similar screws and bayonet slots provided on the abutting ends 3| and 32, re-

' spectively, of the housings.

Housing I9 is provided with the conventional window opening whereby pencil shavings may be removed, the edge ofthe opening being provided with a bracket 33, or other suitable means, for slidingly receiving and engaging a transparent closure member.

The end closures 21 and 3|, of housing l9, are provided with bearings 34 and 35 wherein the shaft, 36, of the pencil sharpener 20 is operably mounted. The shaft portion which operates in bearing 34 is, of course, hollow and adapted to receive a pencil for sharpening, and the end of the shaft portion which operatesin bearing 35 is provided with a groove 31 whereby the shaft 36 may be engaged by a tongue on driving mechanism to be described hereinafter. The shaft 36 is also provided with a shoulder 38 so positioned 'as to permit a slight longitudinal shaft movement (the purpose of which is to be described shaft to disengage the bearings 34 and 35.

Housing 2| is provided with an exterior brack 0 et 39 adapted to slidingly receive and rem'ovably engage sheets of material St, such as calendars, memoranda sheets, name plates, etc.

The ends 32 andZB, of housing iii, are provided with bearings M and 42, respectively, wherein a shaft 43 is operably mounted, the bearings 6i and 62 being in axial alignment with bearings 3d and 35. The end of shaft 53 which is engaged by bearing M is provided with a tongue or clutch M which projects from the shaft 63, and bearing All, and is adapted to engage the groove 3"! of shaft 35, while the end of the shaft which is engaged by bearing #52 is provided with means 65, such as a wheel or crank, for manually rotating shaft 43 which in turn rotates shaft 35 when the latter shaft is pushed longitudinally, bythe insertion of a pencil into the sharpener, into tongue-and-groove engagement with shaft 63.

- n the inner face of the end 82, a non-rotatable cam sleeve 85. constituting a portion of the 1 spring rewind reel 22, is mounted coaxially with hearing ti. This sleeve is provided with a coil type cam M on its inner walls, which cam is engaged by a cam follower 68 rotatably mounted upon the shaft 45. A coil spring 69, encircling the shaft '33, is attached at one end to the cam \fOllOWGl 68 and its other end is attached to a hearing provided member 553' rotatably mounted onthe shaft 53 and fixed to one end of a spool sleeve 50 for rotatably mounting the sleeve coaxially upon the shaft t3 and free to rotate with respect to the ends 28 and 32. At least a portion of the bearing M is cylindrical and its outer surface serves as a bearing upon which one end of the spool sleeve 58 is rotatably mounted.

The spool Ed is intended as a drum or spool for a roll of material such as blotting paper, memoranda paper, etc., which is intended to be withdrawn or unreeled, for use, through a longitudinal opening 52 in housing 2 l The material to be wound upon the drum 50 is attached to an apron 53 which in turn is attached to the spool 50 by means of a flat spring clip 5d having transverse hooking means 55 adapted to pass through eyelets 56 in the apron (see Fig. 5 and engage the spool within holes provided therein. By flexing the spring clip 5% in a direction opposite the hooks 55 they may be withdrawn from the reel aperturesand apron eyelets.

The material to be carried by the apron, and in turn reeled and unreeled. from the spool 50, is

' attached in an overlapping manner to the free end of the apron by a banding clamp 57, as shown in Figs. '5, 9 and 10, which is comprised of a strip of spring steel having its ends bent sharply back upon its face-portion and terminating at a point slightly overlapping each other, whereby one end may be hooked underneath the other. The clamp may be opened by flexing the face portion of the clamp sufliciently to permit one end to pass from under the other. In order to provide additional frictional engagement between the apron, the sheet material, and the clamp, the face-portion of the clamp isprovided on its material engaging side with a raised portion adapted to fit within a depression or hole 58 in the bent back end portion of the clamp. The clamp 51 is of such length as will permit its longitudinal passage through the opening or slot 52 in housing 2| in order that material clamped to the apron may be attached or replaced without removing the spool 50 from the housing 28, as will be described hereinafter.

The housing 2| is provided with a fiat spring 58 attached at one end to the inner face of housing 2! and is retained in a flexed position by the inner material against the opposite edge of the slot 52 at any desired unreeled length. The spring 59 is manually flexed, for the purpose of bringing about the clamping action, by means of a stemmed button 6! attached to the spring 59 and passing through a shouldered or L-shaped slot 62 in housing 2!. The clamp may be locked, in engagement with thematerial which passes through the slot 52, by a downward and thence slight horizontal movement of the button 6! whereby the stem thereof engages the shoulder forming the leg of the L-shaped slot. By a reverse horizontal movement the spring is freed and automatically carries the gripping member Gil back to its normal position. The member 60 and the edge of the slot 52 may also have cutting or perforat-- 53 similar to that of clamp 51, except that itslength exceeds that of the slot 52, to prevent the material from escaping completely into the housing 2i. i I

In the operation of the reel it will beunderstood from the foregoing that the spool sleeve 50 is adapted to receive the cam sleeve 46 as the cam sleeve 66 receives the cam follower 48. By this telescopic movement, of one into the other, the cam causes the cam follower to wind the spring 39. However to prevent an unwinding of the spring 49 by the otherwise rotary-free spool 58, to which the spring is attached, the spool must be held against rotation. This is done by first the apron 53. When the material 5| is unreeled,

by pulling on clamp 63, the reel spring is rewound for the purpose of rewinding the material after it has been withdrawn for use.
